Fabrication of polyvinylidene fluoride/silver nanofiber membrane with antibacterial and anti-yellowing property

At present, nanofiber antibacterial materials, especially silver antibacterial materials, are one of the most popular antibacterial materials. Nanofiber antibacterial materials are the most widely used materials due to their antibacterial spectrum and persistence. In fact, the storage and anti-yellowing properties of nanofiber antibacterial materials are of great concern in the application of industrial and consumer goods. However, there are few studies on the uniform preparation, storage, and anti-yellowing properties of antibacterial materials. Thus, we prepared nanofiber antibacterial materials by adding surfactants and studied the dispersion and storage time of the spinning solution. After spinning and forming the membrane, we tried to study the fiber morphology and environmental factors prepared by different proportions. Finally, we also tried to study the properties of the nanofiber membrane, such as contact angle, anti-yellowing, and antibacterial property. In a word, we explored the basic rules of material preparation, storage, and yellowing resistance so as to provide guidance for nanofiber antibacterial material industrial production.
